OPERATION
The EP160, EP161, EP163, EP165, EP166, EP170 and EP174 programmers provide the operator
with a constant status indication as well as diagnostic information. Programmers with an Engineer-
ing code of 28 or later (e.g.: 9414-28) are compatible with either the ED510 (2 line x 16 character
LCD display with keypad for local access to historical information) or ED500 (8 character LED dis-
play).

For purposes of illustration for this bulletin, we will be looking at the EP160 Programmer
functions and messages associated with the ED510 display module. The ED500 display messages
will be abbreviated versions of those of the ED510. Refer to the suggestions shown in bulletins E-
1001 or E-1101 before proceeding to power the Fireye FLAME-MONITOR system. Items such as
scanner installation, short circuit tests and safety information should be reviewed.
CAUTION: On initial power-up and on restarts following a power failure, the control will
perform self-test diagnostics for 15 seconds.
Start-Up (Normal Cycle), EP160 Programmer
Note: For direct spark ignited oil burners, substitute the words Main-Oil Valve for Pilot Valve.
1. Constant 120 VAC should be wired to the Ll-L2 terminals on the wiring base.
2. The operating control circuits (Ll-13) will close, signaling the burner to start its firing sequence.
3. Assuming the fuel valve end switch (13-3) is closed, the burner/blower motor (terminal M) cir-
cuit is energized. The running interlock (limit) circuit (3-P) will close (e.g.: all limits, interlocks,
etc. are proven).
4. The firing rate motor (Modulator Motor) is driven toward the high purge open damper position
(10-X circuit made).
